Settle down now laddy's Ahem hem:teach:

EXHAUST CO/HC/LAMBDA
(This item does not apply to vehicles registered before 1st January, 1980)
Method of Testing
1. Check visually in the case of 4 stroke spark ignition engines (petrol or gas) that the emission control system is
complete and properly connected and that there are no leaks in the exhaust system.
Pre-Jan 1994 Registrations
2. With the engine at normal operating temperature connect the CO/HC meter as per manufacturer’s instructions.
Raise the engine speed to approximately 2,500 R.P.M. and hold for 20 seconds. Allow the engine to return to idle
and the emissions readings to stabilise. Note the carbon monoxide and hydrocarbon content of the exhaust gases
at normal idle speed.
Post Jan 1994 Registrations
3. For vehicles first registered on or after the 1st January 1994 raise the engine speed to 2,500 R.P.M. or to a speed
specified by the vehicle manufacturer and hold for a minimum of 30 seconds. Check the HC, CO and Lambda
values. If the exhaust emissions are not within the specified limits with the vehicle engine at normal operating
temperature raise the engine speed to 2,500 R.P.M. or to a speed specified by the vehicle manufacturer and hold
for 3 minutes note HC, CO and Lambda values. Allow the vehicle engine to return to normal idle speed and the
exhaust reading to stabilise and note the CO reading.
NOTES:
(a) When checking exhaust emissions the vehicle must be conditioned in accordance with the vehicle
manufacturer's recommendations.
(b) Where it can be established that the vehicle manufacturer’s recommendations on exhaust emissions are
higher than those listed in the reasons for failure then the manufacturers figure should be the criteria used
when deciding whether or not the vehicle passes.
(c) For vehicles tested operating on L.P.G. the hydrocarbon reading must be divided by the propane/hexane
equivalent factor (PEF) which is marked on the hydrocarbon test equipment.
(d) Where vehicles are fitted with twin exhaust systems the higher of the two should be taken.
(e) A HC test is not required on vehicles operating on CNG.
(f) This test should not be carried out where
(a) the oil warning light remains on with the engine running.
(b) the oil level is below the manufacturers minimum level.
(c) the oil level is above the manufacturers maximum level.
